Answer:
Does heart rate affect blood pressure?
A rising heart rate does not cause your blood pressure to increase at the same rate. Even though your heart is beating more times a minute, healthy blood vessels dilate (get larger) to allow more blood to flow through more easily. When you exercise, your heart speeds up so more blood can reach your muscles.
Explanation:
Answer: As your heart beats faster, healthy blood vessels will expand in size to allow increased blood flow, which helps your blood pressure remain relatively stable.

HIV can paralyses the immune system of a person infected by the virus.
Explain why.
Explanation:HIV attacks a specific type of immune system cell in the body. It's known as the CD4 helper cell or T cell. When HIV destroys this cell, it becomes harder for the body to fight off other infections. When HIV is left untreated, even a minor infection such as a cold can be much more severe.
Because HIV can hide inside of cells

A student noticed that when a dog is cut, the dog periodically licks its wounds. Usually
after a few days, the wound begins to heal without ever showing
signs of infection. The
following steps outline the student's line of reasoning:
1. I wonder why the dog's wound doesn't become infected.
2. The dog's saliva must prevent the growth of infection-causing bacteria.
3. I'll obtain a bacterial culture and grow the same kind of bacteria in two identical
culture dishes. Once the bacteria start growing, I'll add dog saliva to only one of the
dishes and leave the other alone. I'll cover both dishes. Then I'll observe what
happens each day for a week.
4. Even after adding the dog saliva to one of the dishes, the bacteria continued to grow
in both dishes over the course of the week. However, the bacteria in the treated dish
grew more slowly than the bacteria in the untreated dish.
5. I think I'll try something else. I'll start with two identical culture dishes, as before, and
use the same kind of bacteria in each dish, but this time I'll treat one dish with dog
saliva before I add the bacteria. I'll observe what happens each day for a week. 12.
For the dog scenario above, what is the control

27. A certain type of toad resembles tree bark with its brown color and rough skin. A certain type of frog, has a bright yellow-green color with red toes and smooth skin. How does the appearance of each organism most likely help them survive?
Answer:
Frogs go brrrrr
Explanation:
If a brown toad is in a forest then it will be harder to spot. If a bright yellow-green colored frog were in the same forest, it would be much easier to spot. So their appearence helps them survive by being harder to spot and allowing them to live and avoid preadators.

If you are building a dichotomous key and you have 10 species to identify, how many couplets should your key have?
A) 04
B) 05
C) O9
D) 10
Answer:
10
Explanation:
easch couplet presents the user with 2 alternatives and exclusive sets of character's.
10 couplets should your key have. If you are building a dichotomous key, and you have 10 species to identify. Hence, option D is correct.
What is dichotomous key?A dichotomous key, a crucial piece of scientific gear, is used to discriminate between diverse species according to their visible traits. Users must choose one of two possibilities to answer a series of questions that make up dichotomous keys.
A dichotomous key in the identification of trees, for instance, would ask whether the tree has leaves or needles. The key then leads the user down one set of questions if the tree has leaves; if the tree has needles, a different set of questions is shown.
The three most prevalent types of dichotomous keys are nested, connected, and branched. Each sentence has the appropriate response written next to it in nested type.
Thus, option D is correct.

access the capabilities of animal and plant cell types owing the presence or absence of chloroplast and cell wall
Answer:At this point, it should be clear that eukaryotic cells have a more complex structure than do prokaryotic cells. Organelles allow for various functions to occur in the cell at the same time. Despite their fundamental similarities, there are some striking differences between animal and plant cells (see Figure 1).
Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not.

A species which is carried into a new location by people is called an invasive species. An invasive species can damage the food chain of an ecosystem.
What is an invasive species?An invasive species is an introduced species which becomes overpopulated and harms the environment into which it is introduced. Although most of the introduced species are neutral or beneficial with respect to other species, an invasive species adversely affect habitats and bioregions, which causes ecological, environmental, and economic damage.

Pleaseeee help!!! (psychology edge) Androgens and estrogens are hormones that impact the sexual response cycle. Write about the four phases of that cycle and explain how the two types of hormones are involved.
Answer:
Females and males each have some amount of the sex hormones, androgens and estrogens. In males however, androgens like testosterone is more dominant and in females estrogens like estradiol are more dominant. The hormones both affect the sexual response cycle. The sexual response cycle has four phases: desire, arousal, orgasm and resolution. The desire phase can last anywhere from a few minutes to hours and includes physical changes like an increase in muscle tension, heartbeats quickening, flushed skin, and an increased flow of blood to genitals. The arousal phase extends to the brink of the orgasm phase, during this phase the changes experienced in the desire phase are intensified along with blood pressure increasing. The orgasm phase generally only lasts a few seconds and is the climax of the sexual response cycle, some characteristics include: Involuntary muscle contractions and spasms, blood pressure, breathing, and heart rate at their highest point, a release of built up sexual tension, and flushed skin. During the resolution phase the body returns to normal, often a sense of wellbeing and fatigue is achieved. To begin the cycle a male need a certain amount of the androgen, testosterone, but high levels in females tend to lead to more sexual thought and desires, typically though, women have relatively low levels of testosterone. In women, estrogens, such as estradiol are more common. Estrogens are produced when a girl starts puberty and helps her reproductive cycle begin. A high level of estrogen in men can lead to a reduced sex drive, loss of hair, or trouble focusing, but a normal level in men is crucial to proper erectile function.
